BDY 630-X | CAS 268725-21-9

BDY 630-X is a fluorescence dye designed for incorporation into fluorescence labeling workflows where long-wavelength emission is advantageous for multicolor imaging and reduced background from shorter-wavelength channels. Its chemical functionality supports conjugation into biomolecule and materials formats used in chemical biology, microscopy, and fluorescence-based assay development, enabling researchers to track labeled targets through standard optical readouts.

1. Fluorescence Labeling Conjugates

BDY 630-X is used by chemical biology and bioconjugation groups to generate fluorescently labeled biomolecule conjugates for downstream imaging and quantitative assays. Researchers typically incorporate the dye into antibody, peptide, or protein labeling pipelines to produce conjugates that can be handled alongside common fluorescence instrumentation for localization studies, binding experiments, and comparative fluorescence readouts. The dye's far-red spectral positioning is especially useful when separating signals from green/yellow fluorophores in multiplex experimental designs.

2. Fluorescence Microscopy Staining

BDY 630-X is applied in fluorescence microscopy workflows for visualizing labeled biomolecular targets in fixed-cell and fixed-tissue imaging experiments, where emission in the red/far-red region helps improve contrast against cellular autofluorescence. Imaging groups use BDY 630-X-labeled conjugates as staining reagents for cellular localization studies, co-localization experiments with spectrally distinct dyes, and fluorescence tracking of prepared biological samples. This use case is common in microscopy method development, where consistent optical performance across imaging sessions is required for reliable qualitative comparisons.

3. Flow Cytometry Fluorescent Probes

BDY 630-X is leveraged in flow cytometry panels as a fluorescent labeling component for analyzing labeled cells or cell-associated biomolecules with instrumentation capable of detecting its emission window. In immunophenotyping and assay development workflows, researchers prepare BDY 630-X-containing conjugates to quantify binding or staining intensity across populations, supporting gating-based analysis and multicolor experiments that benefit from spectral separation. The dye format is particularly relevant for panel design where long-wavelength channels help reduce spectral overlap with brighter short-wavelength dyes.

4. Fluorescence-Based Bioassay Development

BDY 630-X is used in fluorescence assay development to create labeled reagents that report binding events, reagent interactions, or assay readouts through optical intensity measurements. Assay developers incorporate the dye into assay constructs such as fluorescently tagged binding partners, detection reagents, or calibration/trace standards used in plate-based fluorescence workflows. This application is common in research settings where robust, instrument-compatible fluorescence signals are needed for screening, optimization, and comparative studies of assay components.
